I need to run a 12,000 BTU/ 60Hz/ 115 volts/ 1120 watts AC for upto 12 hours a day. I was thinking of serial conecting solar panels upto 60 watts (using silcone diodes) together, and increasing the number of rechargeable betteries, and the watt converter to be able to do so. What are your thoughts? This is to create an off grid AC dog house for a puppy.
